Optical Clearance Effect Determination of Glucose by near Infrared Technique: an Experimental Study Using an Intralipid Based Tissue Phantom
نویسندگان
چکیده
The present paper describes the results of experimentation, carried out on intra-lipid phantom to study the optical clearing properties of glucose. For this intra lipid phantom with different concentration of dextrose levels have been used and the measurement based on selected mathematical parameters have been obtained using indigenously designed amplitude modulated ultrasound & infrared system. The results shows that dextrose minimizes the refractive index dissimilarity between scatterers and their surrounding media, leading to a smaller scattering coefficient, consequently, a shorter optical path. Hence, it is concluded that light clearing effect in relation with dextrose concentration can be principally utilized for the design of amplitude modulated ultrasound & infrared based non-invasive blood glucose meter.

Induction of Localized Hyperthermia by Millisecond Laser Pulses in the Presence of Gold-Gold Sulphide Nanoparticles in a Phantom
Introduction Application of near-infrared absorbing nanostructures can induce hyperthermia, in addition to providing more efficient photothermal effects. Gold-gold sulfide (GGS) is considered as one of these nanostructures. This study was performed on a tissue-equivalent optical-thermal phantom to determine the temperature profile in the presence and absence of GGS and millisecond pulses of a ...
متن کاملEffect of dependent scattering on the optical properties of Intralipid tissue phantoms
The calibration of optical tissue-simulating phantoms remains an open question in spite of the many techniques proposed for accurate measurements of optical properties. As a consequence, a reference phantom with well known optical properties is still missing. As a first step towards a reference phantom we have recently proposed to use dilutions of Intralipid 20%. In this paper we discuss a matt...
متن کاملPhotoacoustic blood glucose and tissue measurements based on optical scattering effect
Non-invasive blood glucose determination has been investigated by more than 100 research groups all over the world during the past fifteen years. Many measurement methods are based on the capacity of near-infrared light to penetrate a few millimetres into human tissue where it interacts with glucose. A change of glucose concentration may change the optical parameters in tissue, with the result ...
